Possessives are forms of nouns, pronouns, or sometimes adjectives, that show ownership or a close relationship between one thing and another. In English, possessives are commonly formed by adding an apostrophe and -s ('s) to a noun, or by using possessive pronouns. They connect the owner to what is owned, providing a clear way to express relationships and belonging in a sentence.
  • Show ownership or belonging.
  • Common forms: 's for nouns, possessive pronouns (my, your, his, her, its, our, their).
  • Important for expressing relationships clearly.
Possessives are forms of nouns or pronouns that show ownership or a close relationship between things.

Noun Possessives

Most singular nouns add 's to show possession, even if the noun ends in s (e.g., the boss's car). For plural nouns that already end in s, just add an apostrophe (e.g., the teachers' lounge). For irregular plurals not ending in s, add 's (e.g., children's toys).
Noun TypePossessive FormExample
Singular'sThe cat's toy
Singular ending in s'sThe boss's car
Plural (ends in s)Apostrophe (')The dogs' owner
Plural (irregular)'sThe children's book
  • Use 's for most singular nouns.
  • For plural nouns ending in s, add only an apostrophe.
  • Use 's for irregular plural nouns.
Add 's to most singular nouns to form the possessive.
For plural nouns ending in s, just add an apostrophe (e.g., 'dogs' → 'dogs'').

Pronoun Possessives

Possessive pronouns replace the noun and make ownership clear without repeating the thing owned. They are: my/mine, your/yours, his, her/hers, its, our/ours, their/theirs.

  • Use possessive adjectives (my, your) before nouns.
  • Use possessive pronouns (mine, yours) alone, without a noun.
Correct possessive pronouns include mine, yours, his, hers, ours, theirs.
Possessive pronouns replace the noun and include forms like mine, yours, his, hers.

Adjectives and Pronouns

Possessive adjectives and possessive pronouns both show ownership, but they are used differently:
  • Possessive adjectives (my, your, his, her, its, our, their) modify nouns:
We brought our books.
  • Possessive pronouns (mine, yours, his, hers, its, ours, theirs) replace nouns and stand alone:
The books are ours.
For more detail, see Adjectives and Pronouns.
Possessive adjectives come before nouns, while possessive pronouns stand alone.
No, possessives include noun forms and possessive pronouns.

Possessives with Compound Nouns and Multiple Owners

For compound nouns, add 's to the end of the whole compound:
  • Mother-in-law's advice
When two or more people share ownership, add 's to the last name only:
  • Jack and Jill's bucket
If ownership is separate, give each person a possessive form:
  • Jack's and Jill's coats
  • For compound nouns, add 's at the end of the compound.
  • For shared ownership, add 's to the last owner’s name.
  • For separate ownership, give each owner a possessive.
For multiple owners sharing possession, add 's to the last owner’s name.
If ownership is separate, use possessives for each owner (e.g., Jack's and Jill's coats).
